MECHANICAL MOVEMENT FOR ADDING-MACHINES.

Application filed. December 28, 1908.

To add whom it may concern.

Be it known that we, JOHN PIRRONG .ilUN'HQR and HENRY Kfi N'rZLEn, citizens of the United States, and residents of Wilkes- Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Mechanical Movements for Addingdvlachines, of which the following is a specification.

Our invention relates to adding machines and more particularly to the means em ployed to actuate the machine when a motor is employed.

in Letters Patent of the United States, No. 902,103, issued to Charles N. McFarland Oct. 2-7, 1.908, there is shown and described a power transmitting or clutch mechanism intended to be employed in the transmission of power from a motor to an adding machine. This mechanism comprises a drum actuated from a continuously rotating motor, a shaft on which the drum is loosely mounted to revolve, a carrier rigidly mounted on the shaft, a control ring mounted to rotate on the shaft and provided with projecting toes, a driving arm eccentrically mounted on the carrier, means for placing a constant tension on the driving arm, a connection between the control ring and the driving arm, a holder or detent adapted normally to keep the driving arm out of contact with the revolving drum inside of which the carrier is mounted, means for interrupting the function of such holder or detent comprising a depressible actuator key. and means also whereby the function of the holder may be automatically restored. In effect, when the actuatorkey of that mechanism is depressed, the clutch shaft is rotated a fraction of a revolution and such. motion is adapted to be transmitted to the operative mechanism of the adding machine. v

This power transmitting mechanism was designed to be employed with the well known Wales adding machine and the form of motor indicated to be employed was an electric motor.

In actual practice it has been found that such motors are not infrequently rendered inoperative either by accident to the motor Specification of Letters Patent.

or to the source of energy, that changes are sometimes made in the nature of the current supplied and yet other circumstances occur which make it desirable to be able to detach and disengage the motor readily from the adding machine, and replace it by another of the same or different type, and also make it desirable to be able to detach the power transmitting devices from the operative parts of the adding machine so that they may remain idle when the machine is operated by hand. Our invention relates to means for accomplishing these purposes. It also renders possible the employment of the simplest form of power transmitting mechanism, one which does not readily get out of order, is positive and certain in its movement, and which necessarily requires much less energy in its use than any mechanism now in use for this purpose.

In the drawings, Figure l is aside elevation, partly in section, illustrating one embodiment of our invention, as applied to a calculating machine, the machine being at rest; Fig. 2 is a side elevation, partly broken away, mechanism disconnected from the calculating machine, which is operable by a handle; Fig. 3 is a side elevation partly in section, showing positions of the motor drive mechanism and connected parts at the end of the fcrwa rd stroke of the main drive shaft; Fig. f is a similar view, showing the rack bar disconnected from the main drive shaft of the machine; and Fig. 5 is a similar View,

showing the positions of the parts during the forward stroke of the main drive shaft. Referring to the drawings, 1 is fthe base of an adding machine and 2 is a part of one of its side frames, of which there are two, one on each side of the machine. 3 is an operative rock shaft or main drive shaft transmitting power to the mechanism of the adding machine. Secured to this shaft, or moving in harmony with it, is a lever indicated at 4, and provided with a stop foot 5 to limit its movement in one direction.

Mounted on a pair of elbow levers 20, which move together. is a depressible actuator bar or starting key 21 adapted to be inc-veil vertically. The levers 20 are adaptshowing the motor drive ed to swing on pivots 22 projecting from the frame 2 of the machine. At their lower extremities they are coupled by a link 23 so that they will move together, and to one of them is pivoted a link which in turn, is pivoted to a crank 26 rigidly secured to a rock shaft 27 A crank 28 secured to the rock shaft 27 is connected by a vertically placed actuator link with a crank 30 mounted on a trip or rock shaft 31 which in turn, is connected to the device by which the function of the holder or detent of the power transmitting mechanism is interrupted and restored. This train of mechanism comprises the motor tripping device.

A motor is indicated at 100. A shaft 101 driven therefrom, as hereinafter describe carries a worm 102 in mesh with a worm gear 103 rigidly secured to a shell so that the gear and shell shall rotate on an intermediate clutch shaft 105 on which they are loosely mounted. A control ring provided with projecting toes 114: and slots 121 is mounted on the shaft. A holder or detent consisting of an arm 151 fast on shaft 31 is adapted to engage the toes 11A and it is pro vided with an arm 153 having a restoring roller 154:. In the Patent No. 902103, above referred to, the coupling and clutch mechanism is fully described and such description.

need not be repeated here. It is suflicient to say that when the actuator bar 21 and link 29 are depressed, the clutch shaft is revolved a fraction of a revolution depending on the number and positions of the toes 114:.

A lock, which forms the subject matter-pf another application for Letters Patent, comprises a locking arm 260 formed of an upward extension of the crank 20. This arm is provided with a slot 32 adapted to engage a pin 33 projecting from the frame of the machine to limit the movement of the arm which has a laterally projecting flange 34.. Loosely mounted to oscillate at a convenient point near the arm 26, for instance on the frame 2, is a cooperating lock plate 35 having a projecting arm 36 with a lateral flange .37 adapted to engage the flange 3%, and a second arm 38 having an inwardly extending flange 39 adapted to be engaged by the stop foot 5. The lock plate is also provided with a slot 810 adapted to engage a pin 11 projecting from the frame A spring 4:3 is adapted to move the arm 30 downward and the arm 38 upward.

Fig. 5 shows the actuator bar in its pressed condition. Arm 260 is in its extreme inner position and rod 29 has rocked arm 30 and shaft 31 and the clutch is thereby actuated. In the resulting movement of shaft 105, roller 15aon arm 153 is cammed forward thereby forcibly moving rod 29 upward and restoring the actuator bar21 to its original position as indicated in Fig. 5 by the dotted lines. This movement occurs 7 soon after the shaft 105 has begun its move ment and before the operating arm a of the machine has completed its oscillation. The upward movement of rod 29 and bar 21 is also accompanied by the forward movement of arm 260 to the position shown in the dotted lines of the figure. As soon as the lug on this arm clears lug 37 on locking arm 30, the latter is drawn downward by the tension of spring l3 to the position indicated by the dotted lines. When the parts are in this position, the actuator bar 21 cannot be depressed as lug 37 is interposed in the path of arm 260 preventing rearward movement thereof. lVhen the arm A returns to its normal position at the end of its oscillation it contacts with the foot 39 on the lower arm 38 of the locking arm 30 and thereby raises the lug 37 out of the path of arm 260, thus permitting the actuator bar '21 to be again depressed. In operation, therefore, as soon as the bar 21 is depressed to cause the actuation of the machine, it is almost immediately automatically restored and locked in its elevated position until the cycle of the machine is completed, whereupon the lock is released.

The motor 101 is provided with an armature shaft 1000 which is adapted'to be detachably secured to the auxiliary worm shaft 101 by means of a coupling. In the form of device shown, this consists of a sleeve 1001 secured to the shaft'101 by a pin or bolt 1002 and which sleeve is recessed at 1003 to engage a pin 100st projecting radi ally from the shaft 1000. This is a form of coupling which permits of a quick engag ment and disengagement of the two shafts. Any suitable form of coupling may, however, be employed.

The power transmitting mechanism is mounted in a sub-frame 1005 and the clutch mechanism itself is arranged within a shell or inclosure 1006 to protect it from dust and injury. The frame is adapted to be detachablysecured to the base 10f the machine by bolts or screws, as indicated at 1007, or in any other suitable manner.

Mounted on the end of the shaft 101 is a motor actuator controller which forms the subject matter of a separate application for Letters Patent and which, in brief, comprises a central hub, secured to or made integral with the shaft, a supporting disk '70, a plurality of radially movable weights 75, each provided with a circumferential flange 700 forming, in efiect, a continuous annular flange adapted to expand under the influence of the centrifugal action of the motor shaft and limited in such expansion by springs 7 9 secured to the separate weights 7 5 through appropriate slots in the disk 70. A locking arm 290 rigidly secured to the rock shaft 31 is provided with a tip 291 adapted to engage the flange 700 when the 1050 secured to the sub .frame 1005.

shaft 101 is at rest. This prevents any movement of the rock shaft 31 and consequently of the actuator bar 29. When, however, the shaft 101 is revolved the centrifugal force of such revolution imparted to the weights moves them and their respective flanges radially and permits the tip 291 to pass inside of such flanges 700 and the rock shaft 31 thereafter to be oscillated.

The means whereby the power imparted to the intermediate clutch shaft 105 is transmitted. to the operative mechanism of the adding machine will now be described.

Mounted 011 the shaft 105 and turning with it is a crank 60 having a plurality of arms 61, each provided at its outer extremity with a suitable roller 62.

Secured to a convenient member of the operative mechanism of the adding machine, for instance, the operative rock shaft or main drive shaft 3 is a gear 370 provided with teeth 371, so that when the gear is 05- cillated, the shaft 8 is oscillated by it.

Mounted intermediate the multiple crank and the gear 370 is a floating reciprocatory power transmitting member (35, one end of which lies in the path of, but not connected to the crank 60, and the opposite end. having teeth to mesh with the gear 3'70, such member serving to transmit the power from the shaft 105 to the shaft 3 when the actuator bar 21 is depressed and the clutch mechanism is rendered operative. This member 65 may, for want of a better term, be called a rack bar although it will be understood that it may have a variety of forms. In the preferred form, it comprises a bar 65 having a slot 66 adapted to engage a supporting and guiding roller 68 pivoted to the clutch inclosure. It also is provided with a depending arm 67 adapted to be engaged on its inner face by the rollers 62 on the crank whereby it is moved in the direction indicated by the arrow in Fig. 1. On its upper front edge it is provided with teeth 69 constituting a rack adapted to engage the teeth 371 of the gear 370.

Arranged beneath the bar or on the side opposite to the teeth 69 is a movable and adjustable support and guide, consisting of a bracket fitprovidcd with a bolt 640, or similar means, whereby it may be secured in a slot or recess 6&1 formed in a bracket The bracket 0-1 carries a roller 642 adapted to engage the edge of the bar 65, and the latter rests upon it. It will be understood that the inner ed 'es 660 of the slot 66 are provided with a flange the better to engage the roller 63 which is preferably grooved, and that the edge 68 is provided with a similar flange to engage a similar groove in the roller 64-2. This construction is simple and tends to secure steadiness of motion of the bar 65.

Then the machine is at rest, the parts are in the positions shown in Fig. 1. If new the motor 100 is energized, its shaft 1000 will be rotated and motion will be imparted to the auxiliary or worm shaft 101 through the coupling 1001 and thence to the intermediate or clutch shaft 105. As the speed of rotation of the shaft 101 increases the weights on the controller are spread apart by centrifugal force and the tip 291 of the locking arm 290 is in a position to be pressed inwardly and to permit the rocking of the shaft 31.

N ow, if the actuator bar 21 is depressed, the crank 20 is rocked and through the pivot 27 and crank 28, a downward motion is communicated to the actuator bar 29. This, through the crank 30, rocks the shaft 31 and, as described in the Patent 902,103, above referred to, moves the holder or detent 151 away from the toe 114 with which it has been in contact to permit the temporary coupling of the shaft 105 to the shaft 101 and the former is turned through. a fraction of a revolution. in the device shown, this is one-half of a revolution because there are two toes 11 1 diametrically placed on the ring. This movement ofthe shaft 105 rotates the multiple crank 60 and brings one of the rollers 02 against the inner surface of the arm 67 and moves it and consequently the member 65 downward, or in the direc tion indicated by the arrow in 1 until, it assumes the position shown in Fig. 3. In this movement, it is guided by the roller in the slot 66 and by the roller 642 on the bracket 6-1 which engages the edge 690. Its teeth 69 in mesh with the teeth 871 of the gear 370 have, however, turned the latter and oscillated the operative rock shaft 3 of the machine, and such shaft has thus had imparted to it a forward stroke. The machine is provided with a heavy main spring 843 which is attached to a convenient part of the frame and to arm 8 1 1 upon shaft 3, as shown in Fig. 5, and serves to retract the shaft 3 to its initial position and to compel its backward stroke. This backward stroke takes place quickly and of course tends, through the gear 370, to bring the bar 65 upwardly to its original position. This operation is also assisted by a spring 600 shown in Fig. 5 the operation of which is quite independent of that of the operative parts of the adding machine or of the clutch mechanism.

During the downward travel of the bar 65 which imparts the forward stroke to the main drive shaft, the arm 153 is shifted to .throw the arm 151 into the path of the succeeding toe 114, to disable the clutch and effect the disconnection of the worm gear link 29 to their normal positions, assisted by the spring 50.

On the return stroke of the main drive shaft 3, the shaft 105 has ceased to rotate,

and the upward travel of bar 05 brin s its too or arm 67 close to the succeeding crank roll 62.

The crank 26 and plate 35 cooperate to lock the bar 21 against depression until the operative rock shaft has reached the end of its rearward stroke. The two flanges 3 1- and 37 are brought together by the spring 43 as the lever 4 moves forward in harmony with the forward movement of the shaft 3, and they are disengaged as the foot 5 of the lever A- engages the flange 39 on the plate 35 and moves the latter away from the crank 26. This locking mechanism forms the subject matter of a separate patent application and constitutes no part of this invention.

It is evident that the operationsdescribed. will be repeated at each actuation of the machine brought about through the depression of the actuator bar 21.

Suppose, now, that it is desirable for any reason that the motor 100 should be replaced by anothermotor, for instance, from one using a direct current to one using an alternating current. The motor is stopped, and its shaft 1000 with the cross pin 1002 withdrawn from the sleeve 1001, and another motor with a different armature shaft may be promptly coupled to it without disturbing any of the other mechanisms of the device.

Suppose that the motor is disabled, or the clutch mechanism gets out of order, or some accident happens to these or other parts below the casing. lVith the usual type of power transmitting mechanism it would be impossible to continue to use the adding machine. This is not so, however, with the described device. The bracket 64 can be moved to carry the roller to the left, as shown in Fig. 4. The bar 65 will then drop away from its engagement with the gear 370 and it will no longer be possible to transmit power through it. If now a handle is placed on the operative rock shaft 3, as indicated in Fig. 2, the adding machine may be operated by hand until such time as it is desired to again operate it from the motor, when the mere adjustment of the bracket 6i and its roller 642 against the bar 65 will again bring about the engagement of its teeth 69 with the teeth 371 of the gear 370 and the parts are at once in position for use.

It will be understood that the term floating used in connection with the rack bar 65, designates a power transmission member which has no positive connection with a coacting mechanism at least, at one end, so as to be free to move independently thereof and uncontrolled thereby.
